Some herbs can be kept as houseplants over the winter. Some that do well are rosemary, thyme, sage, basil, and parsley. It is always nice to have a few pots of these in the kitchen to snip into bowls of soup, salads, scrambled eggs and roasted vegetables and meats. You can dig them up out of the garden in the fall or just grow them in pots all summer that you then bring into the house once the temperature drops.
